Abstract:

Abstract The key factors which effect the impedance of textile-electrolyte interface are analyzed by using the basic structural fabric element simulation based on silver yarns. Electrochemical impedance spectrum method is used to investigate the interface of the system. The factors such as yarn bending and interlocking state, structures, fabric density, yarn continuous state and yarn number which affect the impedance are investigated theoretically and experimentally. It can concluded from the results that: bending and interlocking states of fiber and density of fabric exhibit minor effects on impedance ; the yarn continuous state and yarn number show greater impact on the electrode impedance . Therefore, it can provide a basic principle for the design of the textile- structured electrodes for wearable medical monitoring clothing.
